tweca the lower end of the clothresser earrying bar and the grippingjaws 102, thus securing the cloth-.presser 111 ciiective relav 'tionshipwith the fabric bein acted upon. end to the connection 65 acting tonormally In the use of sewing macines for effect ing embroidery workmuch depends upon the operator and the object in providing improvedstitch controlling means, as herein, is

not only to lessen the responsibility of the vent sizs'of perforationsin the fabric. Supposing the spur eyelet 90 to represent the desiredsize the operator adjusts the fabricwith the spur in the perforation andadjusts the cloth-presser down upon the fabric whernQ if it is desiredto ditch an eyelet of uniform radial stitches. the operator adjusts andby winged nut 71 secures the slide 34- to efiect the desired amplitudeof vibration of the needle, and during the stitchin opera-5 tion thefabric is manually turned a out the nicer-see spur for one, two or morerotations dependent upon the desired character of product, and at thecompletion of the formation of the radial stitches the operator movesthe cam-lever to its vertical position, thus permitting the spring 6l'tomove the camplate 58 in line with the head 42 of the plunger 41 when theoperator, through the manipulation of a suitable treadle, rocks theshaft 55 which causes the cam-plate 58 to move the plunger 41, andthrough the me dium of spring 46 and nut 47, move the segment levertoward the operator at distance suflicient to release the teat 38 fromengagement with the opening 40 and with the stationary lug 106 inengagement with the notch 36 formed in said segment-lever, thus holdingthe latter out of engagement with the segment lever carrier and with theneedle in its outside or depth stitch position or in position to formeither superposed tying stitching or a circular line of stitches aboutthe eyelet in line with the depth stitches, after which the operatorreturns the lever 60 to its former position, it being understood thatradial stitches of varying lengths may be employed through themanipulation of a suitable treadle connected, as previously described,with the rock-shaft 55. It being un derstood that the spring 46 whendepressed is of sufficient strength to overcome the' strength of thespring 52.

When it is desired to do fiat embroidery the spur eyelet is exchangedfor a *needleplate and the cloth-presser removed, the fabric being heldin one form of commonly employed tambour frame which is manually helddown upon the cloth-plate, and as in stitching eyelets, the fabric ismanually presented to the action of the needle. in er fecting the lastmentioned embroidery the teat 38 is transferred from the opening 40 tothe opening 39, thus carryin the segment lever 32 and needle 7 to toleft of I their former positions which causes the nec-,

moved laterally equi distant across the/axis of the previouslypositioned spur 9l'when, through the means previously described, theoperator moves the slide 67 in the guideslot 34 to such position as willeli'ect the desired design or figure, the tying ofi or binding stitchesbeing efiected by allowing the slide 67 to position the axis of the stud66 in aiinement with the axis of the shaft 33,

and during the manualmanipulation of the slide 67 the cam lug 74 iscaused to release the tension action of the'disks '77 more or lessdependent upon theamplitude of vibration of the needle, the tensiondevice 13 acting uniformly upon the thread during the stitchingoperation. a

The lug 107 of the segment lever carrier 28 tracks the slot 35 formed inthe segment lever 32 and acts to limit the downward movement of theslide 67 when effecting radial stitches as in the stitching of aneyelet, but when the teat 38 of the plunger 37 occupies the opening 39in the lever 28 the guide-slot 34 is carried to the left of said lugthus permitting said slide to be moved below said lug as when effectingfiat embroidery, the stop determining the limit of downward movement ofthe slide 67.
